Rumor has it Khan whopped Angulo in sparring in quite a few of the sessions. Not sure how true it is, the weight advantage should reverse it.

ofcourse he did

the weight is to khans advantage since it gives him a speed advantage, the strenght advantage angulo has doesnt mean as much since they only box a few rounds at a time not to mention the bigger gloves and headguards.

the better technical fighter does better in sparring 90% of the time. you cant hurt or bully someone as easily in sparring and you dont have as many rounds to wear them down. your not really focusing on doing any of that either, you work on your skills in sparring.

khan is the more skillful fighter so common sense tells you he would box circles around angulo in the gym. in a fight with small gloves and over the course of 12 rounds things would be diffrent. but ofcourse khan whupps his ass in sparring.
